Bridge CS6 hangs for 2-3 minutes on a certain preview

I am running a new Win7 x64 Professional notebook with an AMD7970m 2GB + IntelHD4000 switchable graphics pair, 32GB of RAM (4GB allocated to PS and assigned 24GB RAMdisk to use as scratch to force all processing into RAM) and have made backups and restore points for every step I made to system changes on this machine. Also, my system temp directories are in the RAMdisk but it takes very little space since it is cleared with each reboot. I literally have it working perfectly with CS4 with any file size that fits in RAM, and all other programs, and had no problems installing CS6. I am running as the primary Administrator account.

However, using PS and Bridge CS6 has been less than optimal. I have the Bridge 'crash-if-not-admin' issue known to many others, so for now I run Bridge as admin and it works. However, when initially starting Bridge, it hangs for 2-3 minutes before I can use it because of a certain .mp4 movie file on my desktop that it struggles to generate a preview for. It only happens on the first startup of Bridge after a reboot, because my RAMdisk with Bridge cache gets erased every boot, but that still doesn't explain why Bridge is incapacitated just to generate that 1 thumbnail. Subsequent openings of Bridge work instantly after the cache preview has finally been generated, however the movie still cannot be played by Bridge.

I think a key piece of information that may help you Adobe fellas to figure this out, is that during this 2-3 minute hang, I notice in ProcessExplorer (an alternative to task manager) that 8-12 instances of dynamiclinkmanager.exe spawn in a cascade of failing instances under Bridge.exe. Notice the 2 instances in the screenshot (red highlights means recently terminated) And after it finishes this fit I can use Bridge all I want just fine.

How could a specific file cause Bridge to hang and perform this same behavior in a repeatable manner? Is there possibly a codec Bridge is not utilizing? I have K-lite mega codec 32 bit and 64 bit so I know I have the proper codecs to view the file outside of Bridge. Missing file permissions? (not sure how theyd be missing since bridge is run as Admin) The file is not corrupt either, I can watch the whole video on multiple media players.

OK I tried renaming dynamiclinkmanager.exe and it no longer hangs with 5DMKIII .mp4 files! I still can't play them even after a full uninstall and reinstall of Quicktime, though.Can anyone explain why Bridge CS6 won't play them?
